Title: Process for the preparation of petroleum wax compositions
IPC: C10G73/06
Filed: 1958-09-15
Abstract: A process for preparing a petroleum soft wax composition comprises the following steps: (i) fractionally distilling a waxy lubricating oil into a plurality of waxy fractions, one fraction being a heavy distillate having a 10-90% boiling range between 430 DEG  and 600 DEG C. and at least one other fraction being a lower boiling range distillate; (ii) separately de-waxing at least these distillates to produce de-waxed oils and slack waxes; (iii) separately de-oiling the slack waxes to produce de-oiled paraffin waxes and oily soft wax fractions; (iv) combining the oily soft wax fractions derived from the heavy distillate and from the lower boiling range distillate; and (v) solvent de-oiling the combined soft wax fraction to give a de-oiled soft wax.  In step (iv) 20 to 40 volumes, preferably 25 to 35, of the heavy distillate soft wax may be mixed with 80 to 60 volumes of the lower boiling distillate soft wax.  The final soft wax may subsequently be blended with a distillate paraffin wax to give a composition containing 10 to 40 volume per cent, preferably 15 to 35 volume per cent of the soft wax.  Several examples of de-waxing and de-oiling solvents are given comprising ketones, alcohols, petroleum naphthas, halogenated hydrocarbons and hydrocarbons.  In an example a large residue was distilled to give a number of fractions including two having 10-90% boiling ranges of 430 DEG  to 523 DEG  C. and 485 DEG  to 580 DEG  C.  These fractions were separately de-waxed with 3 volumes of a mixture of equal volumes of M.E.K. and toluene, and the soft waxes derived therefrom mixed in various proportions.  In another example, three distillate fractions were obtained having 10-90% boiling ranges of 420 DEG  to 460 DEG  C., 460-523 DEG  C., and 485-580 DEG  C. The properties of several compositions of the soft waxes derived therefrom are tabulated.  The soft wax compositions are particularly resistant to cracking when shock-chilled and are particularly useful in the manufacture of milk cartons and paper coatings.  Specifications 806,716 and 839,619 are referred to.

Title: Non-woven fabrics and methods of making them
Inventor: THOMAS GWILYM GARROD
IPC: D04H1/549
Filed: 1964-07-30
Abstract: A nonwoven fabric comprises a fibrous web in which at least 5% (by weight) of the fibres are of heterofilaments consisting of two or more components of which at least one is an elastomer and at least one is potentially adhesive.  The fibres are bonded together at cross-over points by the potentially adhesive component.  The heterofilaments may be crimped.  The elastomer may also be the potentially adhesive component.  The same treatment, e.g. by heat or with a chemical agent, may serve both to crimp the heterofilaments and to activate the potentially adhesive component.  As "hard" (i.e. non-elastomeric) component may be used polyesters, polyamides, polyurethanes, polyureas, polycarbonates, addition polymers such as polyhydrocarbons, and those made from such monomers as vinyl chloride, vinylidene chloride, vinyl acetate, acrylonitrile and their copolymers. Suitable elastomers are block copolymers such as the copolyamides of Specifications 1037474, 1060799 and 692069, polyester-urethanes, and addition polymers, e.g. copolymers of butadiene and acrylonitrile, butadiene and styrene, or butadiene and 2-vinylpyridine, polychloroprene, and copolymers of isobutylene with small proportions of butadiene.  The heterofilaments in continuous filament or staple form may be made into webs by carding, garnetting, air-laying or paper-making techniques, or by high-velocity turbulent fluid jets as in Specification 1088851.  In one example, staple-fibre heterofilaments of copolyamide and polyester-urethane and cellulose pulp are dispersed in water containing a dispersing agent, sheeted out and bonded and shrunk by passage between heated calender rolls.

Abstract: 1478058 Spectrometric analysis MAX-PLANCK GESELLSCHAFT ZUR FORDERUNG DER WISSENSCHAFTEN EV 11 July 1974 [27 Aug 1973] 30703/74 Heading G1A A method of measuring the concentration ratio of two components mixed in a sample comprises the steps of: measuring the reflectance or transmittance at each of three or more optical wavelengths of (a) each component in isolation (b) samples containing respectively each component alone (c) a sample containing the unknown mixture; and calculating the concentration ratio of the components in the sample from these measurements. In a typical double-humped reflectance spectrum for blood, Fig. 1, five wavelengths of interest may be chosen: # 3 , # 1 , # 5 , the wavelength of miniumum reflectance, and lower and upper wavelengths at which the reflectance equals this minimum; and # 2 , # 4 , the lower and upper wavelengths at which the reflectance has maxima, on either side of # 3 . The reflectances of human skin measured at these wavelengths, weighted in turn by each of two predetermined combinations of factors and added, provide two sums whose ratio is equal to the ratio of either oxygenated haemoglobin (HbO 2 ) on deoxygenated haemoglobin (Hb) to the total haemoglobin in the blood behind the skin surface. The predetermined combinations of factors are first found from sets of calibration reflectance measurements at selected combinations of wavelengths as follows:- (a) Oxygenated blood in a cuvette: # 2 , # 3 , # 4  (b) Deoxygenated blood in a cuvette all wavelengths (c) Oxygenated blood in sample skin: # 1 , # 3 , # 5  (d) Deoxygenated blood in sample skin all wavelengths  Sets of equations are given for determining the factors from these calibration measurements. The apparatus Fig. 3 comprises a light source directing either white light or a combination of the five mono-chromatic lights on an area of skin or a sample of blood in a cuvette. Five filters (mounted e.g. on a rotating disc) transmit light reflected from the skin to one or more photo-multipliers which may be provided with synchronous rectifier circuits to direct the signals to respective pairs of amplifiers having predetermined gains AN, B<SP>N</SP> 1  ... ... A<SP>N</SP> 5 , B<SP>N</SP> 5 . The signals from all amplifiers A and those from all amplifiers B are separately summed and fed to a divider which provides a ratio signal for a display or a record.
